The effect of heat treatment on the mechanical properties and residual stresses in a HPDC component of Al-Si-Mn alloy
2007 (English)Conference paper (Refereed)
This study aims at investigating the influence of the heat treatment process on microstructure, mechanical properties and residual stresses in a high pressure die cast (HPDC) of an aluminum alloy component. Two series of high pressure die cast components containing mainly Al -Si 8.4- Mn 0.43 were tested. The first group of components was as cast and the second heat treated. X-ray diffraction, quantitative metallography and mechanical testing methods were used to determine the residual stresses, microstructural features and mechanical properties respectively. Results indicate that the amount of residual stresses varies depending on heat treatment process. The selected heat treatment process can also change the microstructure and mechanical properties.
